My 5 year old and I are loving it. He opens all my cards (he had a great run of getting me new, awesome cards from packs and wonder picks this morning). And I enjoy the simplified battle system - it’s easy to just puts around and try out silly deck ideas against the AI opponents. I will say the format is a little too skewed by ex cards, but I suspect that’s probably true for the full game, as well (not that I would know, given that I haven’t played in about 20 years).
I keep pulling garbage and winning the go first coin flip while losing every other coin flip in the battle… but I keep playing it lol.
I open it occasionally. But i’m not a big fan, because of the simplified battle system. Because of Pokemon Pocket i have sometimes opened Pokemon tcg live the last days. Suit me a bit more.
